By 2010 Samsung believes that 30% of LCD tvs will make use of LED backlights rather than the common fluorescent lamp. The difference Samsung has over the LED units of now is that they plan to use white LEDs with a single diode and a custom coat to produce the backlight , rather than red, green and blue bulbs. Samsung has recently invested in Intermatix who produce the custom phosphor coating for LEDs to produce a uniform color which is required in HDTV sets. They claim this method will cut costs by 40%, expanding to most of the market, rather than just the high end sets.
